For it is so important that a lot of scholars have made and are making a series of studies to their functions. On the basis of corpus-based study, this paper firstly makes a comparison to the usage of adverbial connectors in their writings of the native students and non-native students and then exposes a distinctive gap between these two types of writings in usage of adverbial connectors. In order to help Chinese second-language learners acquire English as well as English native speakers do, this study deeply digs this gap and in further provides several pedagogical suggestions for English teachers and second-language learners.展开更多

The syntax-based language model used in this paper is based on link grammar,which is a high lexical formalism. In order to apply language models based on link grammar in phrase-based models,the concept of linked phrases,an extension of the concept of traditional phrases in phrase-based models was brought out. Experiments were conducted and the results showed that the use of syntax-based language models could improve the performance of the phrase-based models greatly.展开更多

The creation methods of automated design system of a house foundation from blocks are discovered with Unified Modeling Language. Analyzed objects-classes： block, specification, model. Graphical system can design foundation, form specification of objects and create 3D model of house foundation. There are several types and different dimensions of concrete blocks. The program optimally arranges selected blocks so that monolithic parts will be minimal volume. Program selects a house foundation blocks from database by using ActiveX Data Objects technology, which by programming method connects drawing and database. Drawing＇s graphical objects have additional data from which exchange of data between graphical system and database is executed. Visualization system and example of house foundation from blocks project with specifications is presented. Creation problems of automated design system are discussed and conclusions are made.展开更多
